AUTOMATIC e ror non TALKING-MACHINES.

Specification of Letters Patent.

Application filed April 23, 1908. Serial No. 428,723.

To all whom it may concern:

Be it known thatyve, Dnnrr'ros' C. NELSON and Janus /V. Nnnson, citizens of the United States, residing at Marion, in the county of Marion and State of ()hio, have invented certain new and useful Improvements in Automatic Stops for Talking-ltlaohines, of which the following is a specification, reference being had therein to the accompanying drawings.

' This invention relates to automatic stops for talking nutchines. and the object of the invention 18 to provlde means for automaticallystopping the movement of a record support when the sound-reproducing device has reached the end of the record: and to provide adjustable means for controlling the actuating mechanism for the stop.'

With these objects in yic'w our invention consists in certain novel featnres of construction and in certain parts and combinations hereinafter to be described and then more particularly pointed out in the claims,

In the accompanying drawings, Figure 1 1s a side elevation of a talking mach ne equipped With our invention; and F 2;

is a top plan view of the'sarne, with the sound-reproducing device and its support removed.

n these drawings .We have illustrated the preferred form oi. our inventionand have :shown the same as applied to a Well known form of machine embodying a diskrecord,

, but obviously, the device capable of Wide variations from the particular construction herein shown and can be adapted to ditto-rent types. of machines. the talking machine as comprising amotor casing Lhaving mounted thereon the usual turn-table 2'Whieh supports the disk record 3, Ali arm 4 is pivotally supported at its outer end on a bracket 5 carried by the motor casing land extends inwardly over the record 3 and carries at the inner end thereof av suitable sound reproducing device (3 provided with the usual needle 7. stop, such as-a brake 8, which is here shown as of ordinary construction, is provided for controlling the movement of the turntable and the record disk, which is supported,

thereon.

We have here shown A suitable of the record which lies near the center of the disk. lVhen the disk continues to rotate after the pin has reached the end of the record groove it defaces and damages the record, aswell as" causes an unpleasant sound. tions, Wehave devised means for automatically actuating the stop or brake 8 to check the movement of the turn-table and the rec 0rd carried'thereby as soon as the soundreproducing device reaches the end of the record andhave provided means controlled by the movement of this sound-reproducing device over thereco'rd for controlling the automatic stop-actuating mechanism. In the present instance, We have shown the stopactuating mechani's n as comprising a movable member, such as ahar 9, which is preferably mounted upon a base 10 secured to and extending reaii'wardly froin the edge of the motor casing 1. This bar 9 is operatively connected' to the brake 8 and is adapted .to' be moved in such a direction as to op erate that brake. In the preferred construction, the bar 9 is connected to the base 10 by means of suitable links.l l which are pivotally connected at one end to the, bar 9 and'at the other end to a plate. 12, which is rigidly secured to the base 10 near the inner edge thereof. An arm 13 is pivotally connectedat one end to the bar 9 and is connected near its other end to a stop controlling member or actuating lever 14, which isv operatively connected to .the, stop or brake 8. The stop-controlling Patented Jan. 24, 191i."

In'order to overcome these objecmember may be of any suitable character and may be operatively connected to the stop either for the purpose of actuating the same or .for controlling a spring-actuated stop, The controlling member or lever is preferably connected to the arm'13,by' means of a connenting rod 15 pivotally secured at one end to-the arm 13 and having its other end scre\vthre'aded and extending through an apertured lug 16 on the stop-controlling "leverl l, which is-adjust'ably secured thereto means of jam-nuts 17 mounted on the cause the further movement of the bar 9 to meeting said parts one to the other, therelative movement of the two parts being contable.

ed the outer end 23 of the bar'which is proscrew-threaded end of the rod 15 on opposite sides of the aperturcd lug 16. The arm 13 is preferably made adjustable by forming the same in two parts and slidably con-' trolled by the thumb-nut 18.

The present form of connection between the bar 9 and the base causes said bar to move diagonally of the base .10, and in a direction away from the brake and toward the end of-the record, which, in the present instance, is the center of the record disk,- the bar being actuated by a spring 19' which is mounted upon the base 10 and engages the rear side of the bar 9, thus tending to force the same inwardly toward the record. hen the bar 9 reaches a certain point in its diagonal movement, the inner end of the arm 13 is moved beneath the'edge of the turntable and into the path of a projection, such as a pin 13 depending from the under side of the turn-table. The pin 13 coming in contact with the arm 13 moves the same about its pivotal centerand causes the con-. necting rod 15 to actuate'thelever 14: of the brake 8 to check the movement of the turn- The inward movement of the bar 9- is controlled by suitable means connected with the sound-reproducing device 6, and, in thepresent instance, this means comprises a finger 20 supported from thearm l which carries the sound-reproducing device and is mounted thereon by means of a sleeve 21.. The lower end of the finger 20 extends in the path of the bar 9 and serves to control the inward movement thereof. As the sound-reproducing device 6 moves over the record, the arm 4 moves about its pivotal center and the finger 20 is carried with the same and is moved diagonally of the base 10 along a line 'which intersects the line of movement of the bar 9. Consequently, as the sound-reproducing device approaches the end of the record, the finger 20 will have been moved inwardly a distance such as to move'the arm 13 into the path of the stop 13. 'lhust the arm 13 will-be positively moved about its pivotal center and. will actuate the stop-controlling member 14 and the stop 8 will be caused to engage the edge of the turn-table. In order to instantly actuate this brake we prefer to provide the bar 9 with an offset which is so located on the bar that the finger 20'will reach the same and pass off the shoulder formed thereby immediately after the sound-reproducing device reaches the end of the record. This oflset is preferably formed in the bar 9 by formingtho same in two parts, the main portion ofthe bar being provided with a reduced extension 22 upon which is mountsame in its adjusted position thereon. The

width of the portion 23 of the bar 9, which portion is that engaged by the finger 20, is

'greaterlthan the width of the extension 22 to the bar,9. Consequently, ashoulder 25 is formed, this shoulder being of a depth such that when the finger 20 passes beyond the same, the bar 9 will be moved quickly forward and the arm 13 brought into 'the path of the pin on the turn-table, and the engagement of the pin with the arm will actuate the brake and instantly stop the movement of the record. By )making the outer portion 23 of the bar 9 adjustable, the location of the shoulder 25 can be' adjusted to.

accommodate the same to records of different size, thus enabling the machine to .be stopped at the end of the record, regardless of the size of that record. Howeverjinorder to insure that the finger 20 will pass beyond the shoulder 25 immediately upon the sound-reproducing device reaching the end of the record, we prefer to form in the record a groove 26 which forms an extension of the record groove and turns sharply toward the center of the disk, as shown, thus carrying the needle inwardly, and, conse quently, moving the finger 20 quickly through a considerable distance, which, distance is suflicient to insure that-said finger will pass beyond the shoulder .25 and thus permit the bar 9 to move inwardly a distance suilicient to actuate the brake 8. Means are also provided for retaining the bar 9 in its open position againstjthe tension of the spring 19 when it is sddeslncd, and this in .HIIS preferably consistspf'ia. spring-clip 27 secured to the baseglO', and/adapted to en the bar 9 and hold the same against movement when it is desired to render the device inoperative. When it is desired to place the device in operation the bar 9 is moved forward until the forward edge thereof extends beyond the clip 27 and the bar 9 is again under-the control of the spring 19 and the finger 20,

The operation of the device will be obvious from the foregoing description and it will be apparent that we have provided automatic means for controlling the brake or stop mechanism which controls the movement of the record-supporting means; that this means is controlled by a part connected with the sound-reproducing device and is so ad.- justable that the movement of the record will be stopped immediately after the sound-re positively actuated bythe pin on the turntable coming into contact'with the arm which is connected Wi "aid stop-controllmg member, thereby rendermg the operation of the device certain.
